What component of the atom did Rutherford identify in his gold foil experiment?
Through his gold foil experiment, Rutherford identified the nucleus and believed it to be compact but containing the majority of the atom's mass, and the electron cloud. He figured this out based on the deflection of the alpha particles, which rarely hit the nucleus, but sometimes would hit it and deflect at high angles.
Was this answer useful?
Thanks for the feedback!
The conclusions were that the nucleus in an atom must:- (1) Be positive as it repelled the positive alpha-particles (2) Have a high mass, as the deflections were massive … (3) Be very small as only a few of the particles were deflected
Yes , Rutherford's gold foil experiment was about the atomic structure. He bombarded 8000 alpha particles on the gold foil and the source of alpha particle was POLONIUM (an el…ement in periodic table). After bombarding rays, he observed that most of the rays passed without deflecting, and few rays deflected backward. By this , he concluded that most part of the atom is empty. That empty part is also called extra nuclear part or energy levels, shells or orbit . Nucleus lies in the centre of the atom which carries positive charge. It was his assumption which was right. Because two like charges always repel each other. since alpha particles carries positive charge and it can repeled by only positive charge. Electrons revolve in extra nuclear part.One thing that was wrong about Rutherford experiment was his assumption that eletron while revolving in the extra nuclear part continuously radiate energy.
yes there were problems withn rutherford's model but i dont know the problem
That atoms have a positively charged nucleus.
Rutherford discovered that atoms are mostly empty space except for the nucleus at the center of the atom.
In 1911, Ernest Rutherford conducted an experiment that proved that the mass of an atom is concentrated in the center (nucleus) of an atom. It also proved that an atom is most…ly empty space. In his experiment, he emitted positively-charged particles at a piece of gold foil. Many of the particles went straight through, some were deflected, and some were reflected.
Rutherford's results indicated that most of the alpha particles went right through the gold atoms without being affected. He had expected this, because he knew… there must be relatively large space within atoms. However, he was astonished to see that a few alpha particles rebounded from the foil much as a ball rebounds from a solid wall. Rutherford had discovered the nucleus-the tiny, dense, positively charged centre of the atom. This was a tremendously important discovery.
due to its large atomic number
Rutherford was a scientist who shot alpha particles through a very thin sheet of gold foil. The results of this experiment are the following: -Almost all alpha particles passe…d right through the Gold foil -A few alpha particlas were deflected and repelled .....These conclusions show that the majority of the atom of gold is empty space except for a small, positively charged nucleus. This nucleus is the reason why some alpha particlas were deflected(Alpha particles have a positive charge, which is repelled by a positive nucleus).
protons are located in the nucleus of an atom
How did the result of gold foil experiment lead Rutherford to recognize the existence of atomic nuclei?
Rutherford expected the alpha particles to shoot right through the gold foil. At the time it was assumed that an atom was a mix of electrons and protons. When Rutherford s…hot the particles through the gold foil some of the particles reflected back, while most just shot right through. This indicated there was a small dense positively charged nucleus in the atom.

What did Ernest Rutherford conclude about the nucleus of an atom based on his experiments using gold foil?
it was positively charged
1) Atoms were mostly empty space (because most alpha particles went straight through the gold foil) 2) Atoms had a dense nucleus (because few alpha particles bounced straight… back from the atoms) 3) The nucleus of atoms were positively charged (some alpha particles were deflected at large angles)
The Gold Foil experiment demonstrated the (at the time) surprisingresult that atoms had nuclei. The prevaling model for atoms at thetime has been described as "grapes in Jell-…O" (with electrons -"grapes" - suspended in a uniform field of positive charge, the"Jell-O"), and the alpha particles Rutherford (actually, it was hisstudents, Hans Geiger and Ernest Marsden) was shooting at the foilwere expected to pass nearly straight through with only minordeviations. Instead, what was observed was what Rutherford described as "firinga 15-inch shell at a piece of tissue paper and having it come backand hit you," because it turns out that all the positive charge inthe atom is concentrated within a very small region ... thenucleus, and the alpha particles recoiled quite strongly from thisconcentration of charge.
Rutherford proved that atoms: a. are mostly empty space; b. have a small, dense, positively charged nucleus; c. electrons are negatively charged, and far from the nucleus.
That the atom Mostly consisted of empty space.- apex
